Comparative transcriptomic analysis of an evolved and an ancestral wine yeast strains presenting differences in the bioconversion of higher alcohols to acetate esters


ABSTRACT: An evolved strain (ECA5) presented two successive yields of bioconversion of higher alcohols to acetate esters, while its parental strain (EC1118) had a constant yield through the fermentation. Transcriptomic analysis was performed during wine fermentation in SM330 containing 8mg/L phytosterols, at 35 g/l and at 70 g/l of CO2 released. For ECA5, this corresponds to a sample before and one after the change of bioconversion yield. This analysis helped us to understand the different management of lipid source by the evolved strain, which is probably linked to a greater availability in acetyl-CoA.
